Unable to write tags with Mp3tag to M4A that is being played

[Wineroz]

If a file in M4A format is being played in my Winamp, then I cannot write tags in it via the Mp3tag- I first have to stop the file in the player. But at the same time I can edit the tags within the Winamp itself

So is this a normal behavior for M4A files? With FLACs I do not have to stop the in Winamp in order to be able to change data in their tag fields


I am running Winamp 5.8 with Mp3tag 3.03 on Windows 10 Enterprise x64 18362.535. But I do not know what plugin is plugin my M4A files in Winamp, because under

Options > Preferences > Plug-INS > Input

I do not see any name / description with M4A in it

that's normal for really any file and that's because the file is locked as read-only when it's being used. When winamp writes the tag to the file it stops the song very briefly to write it then starts it again. I notice this when I change the ratings on songs

M4a is just a container. It can house different formats, like ALAC or AAC, etc
